Part B: Prevention of fire and explosion
Regulation 4
4 Miscellaneous items of ignition sources and ignitability
4.1 Electric radiators
Electric radiators, if used, shall be fixed in position and so constructed as to reduce fire risks to a minimum.
No such radiators shall be fitted with an clement so exposed that clothing, curtains, or other similar
materials can be scorched or set on fire by heat from the element.
4.2 Waste receptacles
Waste receptacles shall be constructed of non-combustible materials with no openings in the sides or
bottom.
4.3 Insulation surfaces protected against oil penetration
In spaces where penetration of oil products is possible, the surface of insulation shall be impervious to oil or
oil vapours.
4.4 Primary deck coverings
Primary deck coverings, if applied within accommodation and service spaces and control stations, or if
applied on cabin balconies of passenger ships constructed on or after 1 July 2008, shall be of approved
material which will not readily ignite, this being determined in accordance with the Fire Test Procedures
Code.
5 Cargo areas of tankers
5.1 Separation of cargo oil tanks
5.1.1 Cargo pump-rooms, cargo tanks, slop tanks and cofferdams shall be positioned forward of machinery
spaces. However, oil fuel bunker tanks need not be forward of machinery spaces. Cargo tanks and slop
tanks shall be isolated from machinery spaces by cofferdams, cargo pump-rooms, oil bunker tanks or ballast
tanks. Pump-rooms containing pumps and their accessories for ballasting those spaces situated adjacent to
cargo tanks and slop tanks and pumps for oil fuel transfer shall be considered as equivalent to a cargo pumproom
within the context of this regulation provided that such pump-rooms have the same safety standard as
that required for cargo pump-rooms. Pump-rooms intended solely for ballast or oil fuel transfer, however,
need not comply with the requirements of regulation 10.9. The lower portion of the pump-room may be
recessed into machinery spaces of category A to accommodate pumps, provided that the deck head of the
recess is in general not more than one third of the moulded depth above the keel, except that in the case of
ships of not more than 25,000 tonnes deadweight, where it can be demonstrated that for reasons of access
and satisfactory piping arrangements this is impracticable, the Administration may permit a recess in excess
of such height, but not exceeding one half of the moulded depth above the keel.
5.1.2 Main cargo control stations, control stations, accommodation and service spaces (excluding isolated
cargo handling gear lockers) shall be positioned aft of cargo tanks, slop tanks, and spaces which isolate cargo
or slop tanks from machinery spaces, but not necessarily aft of the oil fuel bunker tanks and ballast tanks,
and shall be arranged in such a way that a single failure of a deck or bulkhead shall not permit the entry of
gas or fumes from the cargo tanks into main cargo control stations, control stations, or accommodation and
service spaces. A recess provided in accordance with paragraph 5.1.1 need not be taken into account when
the position of these spaces is being determined.
5.1.3 However, where deemed necessary, the Administration may permit main cargo control stations,
control stations, accommodation and service spaces forward of the cargo tanks, slop tanks and spaces which
isolate cargo and slop tanks from machinery spaces, but not necessarily forward of oil fuel bunker tanks or
ballast tanks. Machinery spaces, other than those of category A, may be permitted forward of the cargo tanks
and slop tanks provided they are isolated from the cargo tanks and slop tanks by cofferdams, cargo pumprooms,
oil fuel bunker tanks or ballast tanks, and have at least one portable fire extinguisher. In cases where
they contain internal combustion machinery, one approved foam-type extinguisher of at least 45 / capacity
or equivalent shall be arranged in addition to portable fire extinguishers. If operation of a semi-portable fire
extinguisher is impracticable, this fire extinguisher may be replaced by two additional portable fire
